There's has been a rollercoaster romance, with more downs than ups. But when, at the end of last season, Blair finally picked Chuck... the Gossip Girl faithful breathed a sigh of relief. However, it wasn't a done deal, so they're still waiting for a happy ending... and this could be it.

Exhausted: The actress at one point appeared exhausted, hunching over in between takes

Leighton Meester was spotted filming in a beautiful pale blue beaded gown, with stunning silver leaf headdress today, while Ed Westwick, who plays Chuck, matched the colour on his suit lapels. He was spotted filming a scene where he looked to be running, perhaps to his own wedding, while Blake Lively's Serena carried a bridal bouquet. In a new interview, Meester opened up about saying goodbye to the drama series. 'I think it's ending at a beautiful, perfect time,' Meester told Vulture. 'But it's [also] because our contracts are up. I don't think anyone wants to stay after their contracts.'

Meester also admitted that working on the same project for six years can become 'sort of tedious' - and says she now wants to 'move beyond' Gossip Girl. She added: 'It's been an amazing tool to learn from, and I owe pretty much everything... to Gossip Girl. 'But I could say, somewhat, [that] it's my personal growth that has made me want to move beyond it. 'I was 20 when I started, and I'm 26 now, so you don't want to be doing the same thing over a period that long.'
